摘要： 目的对云南省景东无量山自然保护区山地蚤类群落的垂直分布格局与区系特征进行调查研究。方法以鼠夹和电猫捕捉小兽,分别收集其体寄生蚤后进行分类和统计分析。结果共采获蚤类507只,隶属于5科15属26种。其中东洋成分有19种(73.1%),占主导地位;其次为古北成分,仅有5种(19.2%);其他2种(7.7%)为广布种;它们之中约有58%的种类(共15种)为横断山特有种。结论经蚤类群落的物种多样性、均匀度和优势度指数进行测定和比较后看出,无量山不同森林植被带蚤类群落的物种多样性最高位于明针叶林和湿性常绿阔叶林带,而最低位于寒温性亚高山灌丛草甸带,蚤类群落多样性随着海拔高度的上升呈递减的趋势。此外,对该山脉蚤类的区系特征、它们与宿主的关系进行了陈述和比较,还对滇西北、滇西南山地蚤类与宿主动物的区系特征及分布规律等问题进行了分析和讨论。

Abstract: Objective To investigate the vertical distribution characteristics and Fauna of flea in the Wuliang Mountain Nature Reserve in Jingdong.Methods Trap for small mammals in November December,1998.Results A total of 507 individuals belonging to 26 species,15 genera and 5 families was collected.19 species(73.1%) are oriental forms,5 species( 19.2%) are palaearctic forms,and 2 species(7.7%) are wide spread forms.On the other hand,the flea fauna of Wuliang Mountain shows a high degree of endemicity(15 endemic species of Hengduan Mountains area,accounting for 58% of total species discovered).The species diversity,evenness and ecological dominance indices of flea communities in 4 main ecological environments were measured and compared.Conclusion According to the results of investigation,the diversity of flea communities is the highest in the Warm taiga and Wet evergreen broadleaf forest and lowest in subalpine shrubberg and Grasslands.The species diversity index decreased gradually with the ascending altitude.In addition,the characteristics of flea and hosts fauna and the boundary line between Palaearctic and Oriental Realms in Hengduan Mountains of Northwestern and Southwestern Yunnan were also analyzed and discussed.
